Ok, let me preface by saying, I know I should be check my local code, AHJ, what have you, but I'm hoping someone can simplify what I'm reading in the NEC (250.58) which I think is telling suggesting I have to use my houses grounding rod for my add-on 100W solar system that is only being used to...

Newbostonconst, unless I'm mis understanding something, a DC-Ground fault protector is now required on all PV systems. The GFP I am using in the attach image above is a MNDC-GFP63, and Midnite Solar provides a wiring diagram (see attached manual, first page) that instructs you to wire it that...

I do not understand why I need to explain how I plan to use the water pump in my application. It’s irrelevant to mention that if my purpose of this thread is for something else. Instead of attacking someone seeking help, why not try to help me understand why that information is so critical in...

Yes, my application would be permanently installed and connected to a battery. Also, I noticed most of the components you listed you purchased for your application are din rail components. For my DIY tote application, as I mentioned, most of my electrical components are screwed down to a wood...

For those suggesting the heading mat option, do you all run the heading mad off the same battery source you are trying to keep warm, or do you use a different power source?

I'm tried searching the forums here but have not found any solid answers. My conditions: Highest Temp: 90-100F Lowest Temps: 20-30F Battery location: Under a deck outside, and not exposed to sunlight. I hear some people are using heat mats and insulation but I am looking for a 12v heating mat...

Not exactly, I'm basically describing or implementing something like what FilterGuy & Midnite Solar included in their GFP diagrams. (see link below for FilterGuy's post on Ground Fault Protection On Solar Panel Arrays)...

No, the pump will not run continuously. This diagram is not focused on that end of the application, only the solar, breakers, gfp, grounding rod, etc. I'm also not concerned about run time in this topic. Hey Boondock, the pump has a switch, but as I mentioned to iamrich, this topic post isn't...

I'm building an off-grid shed, that will have 800W+ of aluminum framed solar panels installed on a metal roof. For simplicity, I will have the panels connected to a Bluetti/Ecoflow power station. From the power station, I want to connect one of the AC plugs to a small sub-electrical panel that...

Thanks for the reply. I read all 4 guides FilterGuy wrote and they were useful but did add more complexity to what I thought would be a simple system. I'm trying to follow the NEC guidelines to a reasonable point, and I am fine with hooking up the GFP just to learn more about it and be...

Hi all, Let me try to explain my current setup without an image: I have a 100 Watt Renogy solar panel, that will be attached to a Renogy metal mounting bracket, that will be attached to the side of a wooden post. I have a cheap outdoor-rated Walmart plastic tote that is currently housing my...

Thanks for sharing your thoughts on this. What lead me to the 250.58 section is the 690.47 section of the NEC (version 2017) which part of it states the following that I feel my application may fall into: (A) Buildings or Structures Supporting a PV Array. A building or structure supporting a...

This is what I'm thinking as well. Is it once I have a system that is over 50V that I need to probably revisit this subject about grounding and really try to follow it closely? I know you aren't licensed, but I'm sure you know 10x times more about this than I do, and I'm trying to keep this...

Good information. The more I think about the project, the more I am starting to maybe go a similar route you are mentioning just to somewhat maintain a professional look. What type of enclosure would you use for the battery? I've seen a few but just curious from a person already into solar.

I'm reading through the 2017 NEC and looking at 690.13 which states the following: Means shall be provided to disconnect the PV system from all wiring systems including power systems, energy storage systems, and utilization equipment and its associated premises wiring. Attached you can find my...

Correct, so since my panel is attached to part of my house/building (it is attached to the deck that is attached to the house), I need to tie my panels to my house's grounding system which my beginner's brain :unsure: is saying that would be the grounding bus bar or grounding rod. Based on your...

So it seems like the disconnect is primarily for allowing the fire dept. or someone to quickly disconnect the solar panel/array from the system (both positive & negative conductors from the panels) regardless if the system is grounded or not? I also noticed many diagrams that included the...

It is mounted on the wooden wall for my upper outside deck, so not quite attached to the house, but attached to the lower portion of my 2nd level outside deck. If you are about 5.5' or taller, you could probably touch it, so I definitely think the panels/mounting system needs to be grounded...

I must say, this is probably the best common sense answer I have found that may be related to my application. :unsure: ?

I always seem to have a hard time with that statement as I thought the NEC is the electrical code everyone should be following, it's just some states will follow different versions? I live in TN. Who could you typically call in your county to help point you in the right direction if you are...

Hi all, I've reviewed several grounding related documents here on this website, and yes, even the ones written by FilterGuy and the popular grounding video on YouTube. Still have some doubts, but hoping to clear some concerns up in this post. I really need some help confirming if I have the...
